snoluver - normal is a sliding scale!?!
I have no clue what is and isn't normal anymore with kids these days. But - if you're gonna lead a horse to water...or as the case may be a kid to a bike park, he's gonna go! My oldest was building ramps at 3 when there were still boys in my 'hood who didn't have training wheels off at 6. I have a 3 speed freak boys...and a ramp? well, that just gets ya goin faster, right? I think it's cool and I think it's cooler still that ya caught it on vid - will be fun to show him when he gets older.
frnash - too true on the road rash. My oldest still pulls those crash stories out of his arsenal for papers in middle school.
nic - agree with PR1...that's cute! It would be nice to not have total speed freaks in the house who might be interested in saying "Hey! Look at THIS!" instead of "HEY! Look at ME!"
